JAR-TO P.

SPECIFICATION forming part of Letters Patent No. 592,676, dated October 26, 1897.

Serial No. 6 Ll,947. (No model.)

To all whom it TVMLZ/ conoernq Be it known that I, HARRY WEAVER, a citizen of the United States, residing at York Haven, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Jar-Tops; and I do. declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to caps or covers for fruit jars, cans, and the like, and has for its object to provide a cap or cover which can be applied to jars or caps of ordinary construe-Q tion in common use which have a screw-neck at the upper end and which willadmit of easy application to the jaror can and effectually seal the contents of the vessel when the cap is properly applied;

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the construction and the combination of parts hereinafter particularly described, and then sought to be specifically defined by the claims, reference being had to the accompanying drawing, forming a part thereof. v In the accompanying drawing the numeral 1 designates a jar or can of any approved pattern and provided at its upper end or neck, with screw-threads or ribs 2, which may be molded with the jar or otherwise formed thereon.

The numeral 3 designates a screwcap adapted to engage the screw-threads 2 and formed of iron or other suitable material and provided at its upper end with an outwardlyeXtending flange or lip 4, which will constitute a seat for a rubber gasket 5 and for the cap or cover proper, 6, and also serve to receive the inwardly-extending hooks 7 of aclamp 8, which may be made of ironor other suitable material and which gnay have four or other desired number of arms, as illus-' trated. The under side of the cap or cover 6 is formed with a lining 9 of zinc, so as to prevent oxidation on its under surface in case the contents of the jar or can should come in contact with the under surface of the cap or cover. The cap or cover 6 is connected to the clamp 8 by means of a screw 10, the threads of which will engage threads formedin the clamp 8, and the lower end of which will besuitably swiveled to the cap or cover 6.

i In application the screw-cap 3 is screwed onto the neck or upper end of the jar or can 1, and a rubber or other gasket 11 is placed between the lower edge of the screw-cap and the body of the can or jar, preferably beneath the lowermost thread or rib of the screw-neck 2, so as to form an elastic and airtight connection between the screw-cap and neckof the jar or can. The rubber gasket 5 is then placed upon the flange or lip 4, which constitutes a seat, and the cap 6 is then placed in position so as to rest upon the gasket 5, and the lo wer hook ends of the arms of the clamp 8 are placed beneath the lip or flange 4, and the screw 10 is turned so as to firmly seat the cap or cover 6 upon the flange 4 and its superimposed gasket, so as to securely clamp the cap or cover to its place. The under side of the flange or seat 4is preferably inclined or beveled, as shown, so as to afford a firm bearing t'or the hook 7 of the clamp 8, and thus guard against the possibility of the hooks of the clamp being accidentally disconnected from the flange or lip.

In the event of the jar being broken or the can nnfitted for use the screw-cap 3 can be disconnected from the threads of the jar or can and applied to another jar or can and the parts used as before. It will thus be observed that the device is adapted for long service and will save the expense of purchasing an entirely new set in the event of the jar or can becoming unfitted from any cause forfutureuse. It will also be observed that the screw-cap 3 willserve as a protection for the screw-neck of the jar if the latter be formed of glass or like material, and also that even when the jar iscomposed of glass or like material a metallic flange or lip for the screw-clamp to engage with is provided, thus enabling greater pressure to be applied than could be done if the flange or lip were made of glass or like material the same as the body of the jar.

The screw-cap, the cover proper, and the clamp can be made to be sold as an article of merchandise separate from the can or jar, and thus the householder can be provided with one whenever necessary, or if the jar should become unfitted for use anotherca-n be procured and the screw-cap and cover of the old jar or can be used in connection therewith.

I have illustrated and have described with particularity the preferred details of 0011- struction and arrangement of the several parts, but it is obvious that changes can be made therein without departing from the essential features of my invention. Y

Having described my invention and set forth its merits, what I claim is 1. The combination of the cap adapted to be applied to the neck or upper end of a jar or can and provided with a laterally-extending lip or flange to constitute a seat for the cover and a lip for the ends of a clamp to engage with, a cover adapted to rest upon the seat of the cap, a clamp adapted to engage the under side of the flange of the cap, and

means for holding the clamp to said flange and the cover to its scat, substantially as and for the purposes described.

2. The combination of the screw-cap adapted to be applied to the neck of a j aror can and provided with a laterally-extending flange at its upper end, a cover provided with a lining of zinc and adapted to rest upon said flange of the cap, a clamp adapted to engage the under side of the flange to the cap, and a screw connecting the clamp and cover to hold the parts in place, substantially as and for the purposes described.

3. The combination of a screw cap provided with a laterally-extending flange at its upper end having an inclined orbeveled lower face, a cover adapted to rest upon said flange of the cap, a clamp having hook ends to engage the under beveled surface of the flange to the cap, and a screw connecting the clamp and cover, substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY XVEAVER.
